What is the frequency of the function f(x)?
Express the answer in fraction form
What is the period of the function f(x) shown in the graph?
First one :
In the form Acos(Bx) + C
We can find this as follows
B = pi
B = 2pi / period
pi = 2pi/ period rearrange
period = 2pi / pi = 2
Andd the frequency is 1 / period = 1 / 2
Second one :
The period is π
The frequency is : 1 / period = 1 / π
